COHERENTLY SYNCHRONIZED OXIDATION AND DEHYDROGENATION OF CYCLOHEXANE BY HYDROGEN PEROXIDE
Journal Title: Azerbaijan Chemical Journal - Year 2017, Vol 0, Issue 3
Abstract
Inducing effect of hydrogen peroxide on synchronous oxidation reaction is accompanied by the occurrence of two interconnected and interacting reactions. The reaction of Н2О2 decomposition (primary) generates the leading active and free radicals in a system. During the interaction of active and free radicals with the substrate, the conversion of the substrate occurs in the secondary reaction, coherently-synchronized with the primary one. The mechanism of such coherently syn-chronized reactions is being examined in the process of cyclohexane oxidation with hydrogen peroxide in homogeneous and heterogeneous systems. The process of coupling dehydrogenation of cyclohexane to cyclohexene and cyclohexadiene with hydrogen peroxide was carried out without catalyst. This process was also carried out at a fairly low temperature in a heterogeneous catalytic system. Biomimetic catalyst, which simulates the basic functions of the enzyme group of oxidoreductase – cytochrome P-450, was used as the catalyst here. Characterized by its highly active and selective action these biomimetic catalysts are synthesized based on iron-porphyrin complexes. Based on this experimental researches, the complex reaction, consisting of parallel-sequential oxidation and dehydrogenation re¬actions, which are coherently synchronized, proceeds during the process of cyclohexane oxidation with biomimetic catalyst
